Beginning with version 10.0.0, the name of the library is WFDB. All
earlier versions were named DB. All library symbols have been similarly
renamed, with WFDB
and wfdb
replacing DB
and db
everywhere, in names of library functions, constants, type and structure
definitions, library source file names, and names of environment variables
(e.g., the DB environment variable is now the WFDB environment variable).
Version 10.0.0 of the WFDB library is functionally identical with the
final release (version 9.7.4) of the DB library, except for the name
changes. It should be possible to recompile existing applications
written for DB library version 9.x without modification, and to link
them with WFDB library version 10.0.0. This is possible because two
sets of #include
files are provided with the WFDB library. The
first set, accessible via #include <wfdb/...>
, works with
applications written as described in this guide. The alternate set,
accessible via #include <ecg/...>
, is compatible with DB 9.x
applications as described in previous editions of this guide.
